As I've said before, many who call for efficiency generally mean government agencies doing more for even less money. But then some of these same people complain about the cost of doing something more efficiently.
For example, light rail is more efficient than bus service. Except for articulated buses, buses with a single driver are limited to carrying about forty passengers. On the other hand, a light-rail car can hold sixty passengers, and at peak times more cars can be added, greatly increasing driver efficiency.
However, many who want efficiency don't want to subsidize light rail or any public transportation. They don't want to "take away" people's "freedom" to drive cars. One vehicle, one driver: is that efficient? In order to accommodate all these vehicles, their drivers expect government to build bigger, wider faster highways. Oh yes, these drivers don't want them to be toll roads; that would make them more inefficient. Of course, these roads are so convenient that more and more drivers use them eventually slowing traffic! And of course, the taxes dedicated to the roads are insufficient, and so other taxes have to pay for them. And the base for local taxes to pay for them has been reduced because houses and businesses have been removed to make way for ever wider highways. Think of how many hundreds of houses would fit in an interchange like 35E and 694 in the Twin Cities. And bulldozing houses in the cities means that houses have to be built farther out, which means more people have to drive longer distances to get anywhere, which means bigger highways have to be built, ...
Extreme anti-tax people think all roads should be privatized. Let's see, the roads will need devices to scan for paid subscriptions, and toll booths to collect from non-subscribers. Can you imagine having a toll booth every few blocks? That would certainly decrease efficiency. Of course, over time all the toll roads in an area would be run by a company that does not answer to the public, only its shareholders. To increase profits, the company would have to decrease maintenance. Since the customers have no other choice, they will have to put up with the bad roads.
Be careful what you ask for!
